However, this high level of freedom in sound design came at the price of a huge increase in the number of parameters required, meaning that the PAMS was not yet suitable for commercialization as an instrument that the average user could program. / In order to resolve this issue, the Yamaha developers decided to simplify the synth's tone generator design by having the modulator and carrier envelope generators share common parameters. They also reduced the number of algorithms—or operator combination patterns—to 32.
475: 545:, "The synthesizer market was tiny in the late 70s. No one was selling 50,000 of these things. It wasn't until the Yamaha DX7 came out that a company shipped 100,000-plus synths." Smith said the DX7 sold well as it was reasonably priced, had keyboard expression and 16 voices, and was better at emulating acoustic sounds than competing products. Chowning credited the success to the combination of his FM patent with Yamaha's chip technology. 2027: 433: 1869: 1115:
In 1967, John Chowning, at Stanford University, accidentally discovered frequency modulation (FM) synthesis when experimenting with extreme vibrato effects in MUSIC-V. ... By 1971 he was able to use FM synthesis to synthesizer musical instrument sounds, and this technique was later used to create the

on its top panel. / As its name suggests, the PAMS created sound based on various calculation algorithms—namely, phase modulation, amplitude modulation, additive synthesis, and frequency modulation (FM)—and from the very start, the prototype supported the storing of programs in memory.

The DX7 was the first commercially successful digital synthesizer and remains one of the bestselling synthesizers in history. According to Bristow, Yamaha had hoped to sell more than 20,000 units. Within a year, orders exceeded 150,000 units, and Yamaha had sold 200,000 units after three years.

described its interface as "nearly impenetrable", with "operators, algorithms and unusual envelopes ... accessed through tedious menus and a diminutive display". Rather than create their own sounds, most users used the presets.

Kakehashi later said Yamaha were the natural partners in the venture, as they had the resources to make FM synthesis commercially viable. 1614: 718:, throughout the mid-1980s, "Yamaha flooded the market with a plethora of low-cost FM synths." In 1987, Yamaha released the DX7II, which did not match the success of the DX7. Further successors included the 305:, California. FM synthesis created brighter, glassier sounds, and could better imitate acoustic sounds such as brass and bells. Yamaha licensed the technology to create the DX7, combining it with 696:. In later years, the DX sounds came to be seen as dated or clichéd, and interest in FM synthesis declined, with second-hand digital synthesizers selling for less than analog. The development of 458:

At the time of release, the DX7 was the first digital synthesizer most musicians had used. It was very different from the analog synthesizers that had dominated the market. According to

Its presets constitute "struck" and "plucked" sounds with complex 559:, its "spiky" and "crystalline" sounds made it "the perfect antidote to a decade of analog waveforms". It was praised for its accuracy in reproducing 312:
